In this problem, we have a bag with:

• 25 red marbles,

,

• 35 blue marbles,

,

• 20 white marbles.

The probability to pick a blue marble is given by:


P(\text{blue})=\frac{\text{\# of blue marbles}}{\text{total \# of marbles}}=(35)/(25+35+20)=(35)/(80)=0.4375=43.75%.

Answer

The probability to pick a blue marble is 43.75%.
